1 1219 136 EXPOSURE TO ADVERSE EVENTS AND ASSOCIATIONS WITH STRESS LEVELS AND THE PRACTICE OF YOGA: SURVEY FINDINGS FROM A POPULATION-BASED STUDY OF DIVERSE EMERGING YOUNG ADULTS. OBJECTIVES: THIS STUDY EXAMINES THE PREVALENCE OF EXPOSURE TO ADVERSE EVENTS AND ASSOCIATIONS WITH STRESS LEVELS AMONG A DIVERSE POPULATION-BASED SAMPLE OF YOUNG PEOPLE. THE STUDY FURTHER EXPLORES WHETHER THESE VULNERABLE POPULATIONS, WHO HAVE THE POTENTIAL TO BENEFIT FROM THE MIND-BODY PRACTICE OF YOGA, ENGAGE IN A REGULAR YOGA PRACTICE. DESIGN: EAT 2018 (EATING AND ACTIVITY OVER TIME) IS A POPULATION-BASED STUDY IN WHICH SURVEY DATA WERE COLLECTED FROM 1568 ETHNICALLY/RACIALLY DIVERSE (81.2% NONWHITE) EMERGING YOUNG ADULTS (MEAN AGE: 22.0 +/- 2.0 YEARS). RESULTS: EXPOSURE TO ADVERSE EVENTS WAS HIGHLY PREVALENT. FOR EXAMPLE, 43.9% REPORTED AT LEAST ONE ADVERSE CHILDHOOD EXPERIENCE (ACE) (E.G., PHYSICAL, EMOTIONAL, OR SEXUAL ABUSE BEFORE AGE 18), WHEREAS 40.1% REPORTED EXPERIENCING DISCRIMINATION. EXPOSURE TO ADVERSE EVENTS WAS ASSOCIATED WITH HIGHER STRESS LEVELS. PRACTICING YOGA AT LEAST 30 MIN/WEEK WAS REPORTED BY 12.7% OF THE POPULATION, WITH VARIATION ACROSS SOCIODEMOGRAPHIC CHARACTERISTICS. YOUNG ADULTS EXPOSED TO ADVERSE EVENTS WERE EITHER MORE OR SIMILARLY LIKELY TO PRACTICE YOGA THAN YOUNG ADULTS NOT REPORTING ADVERSE EVENTS. CONCLUSIONS: THE HIGH PREVALENCE OF EXPOSURE TO ADVERSE EVENTS AND ASSOCIATIONS WITH HIGHER LEVELS OF STRESS POINTS TO A NEED FOR PUBLIC HEALTH INTERVENTIONS. THUS, IT WAS PROMISING TO FIND THAT YOUNG PEOPLE EXPOSED TO ADVERSE EVENTS, WHO MAY HAVE GREATER EMOTIONAL BURDENS, PRACTICE YOGA AT EQUAL OR GREATER PROPORTIONS TO THOSE WITHOUT THESE EXPOSURES. GIVEN THE POTENTIAL BENEFITS OF YOGA FOR POPULATIONS LIVING WITH HIGH STRESS, IT IS IMPORTANT TO DEVELOP FURTHER OUTREACH EFFORTS AND PROVIDE ACCESSIBLE, ACCEPTABLE, AND AFFORDABLE OPPORTUNITIES FOR PRACTICING YOGA.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
2 1440  35 INCREASED HATHA YOGA EXPERIENCE PREDICTS LOWER BODY MASS INDEX AND REDUCED MEDICATION USE IN WOMEN OVER 45 YEARS. BACKGROUND: YOGA HAS BEEN SHOWN TO HAVE MANY SHORT-TERM HEALTH BENEFITS, BUT LITTLE IS KNOWN ABOUT THE EXTENT TO WHICH THESE BENEFITS ACCRUE OVER A LONG TIME FRAME OR WITH FREQUENT PRACTICE. AIMS: THE PURPOSE OF THIS STUDY WAS TO EXAMINE THE EXTENT TO WHICH BODY MASS INDEX (BMI) AND MEDICATION USE IN A SAMPLE OF FEMALE YOGA PRACTITIONERS OVER 45 YEARS VARIED ACCORDING TO THE LENGTH AND FREQUENCY OF YOGA PRACTICE. MATERIALS AND METHODS: WE ADMINISTERED ONLINE SURVEYS TO 211 FEMALE YOGA PRACTITIONERS AGED 45 TO 80 YEARS. WE USED REGRESSION ANALYSES TO EVALUATE THE RELATIONSHIP OF EXTENT OF YOGA EXPERIENCE TO BOTH BMI AND MEDICATION USE AFTER ACCOUNTING FOR AGE AND LIFESTYLE FACTORS. WE ALSO CONDUCTED COMPARISONS WITH 182 MATCHED CONTROLS. RESULTS: PARTICIPANTS HAD PRACTICED YOGA FOR AS LONG AS 50 YEARS AND FOR UP TO 28 HOURS PER WEEK. THERE WERE SIGNIFICANT INVERSE RELATIONSHIPS BETWEEN YOGA EXPERIENCE AND BOTH BMI AND MEDICATION LOAD. THESE SIGNIFICANT RELATIONSHIPS REMAINED AFTER ACCOUNTING FOR AGE AND LIFESTYLE FACTORS. WHEN WE COMPUTED YOGA EXPERIENCE IN TERMS OF TOTAL CALENDAR YEARS, WITHOUT ACCOUNTING FOR HOURS OF PRACTICE, SIGNIFICANT RELATIONSHIPS DID NOT REMAIN. HOWEVER, THERE WAS NO OBESITY IN THE 49 PARTICIPANTS WITH MORE THAN 25 YEARS OF YOGA PRACTICE. YOGA PRACTITIONERS WERE LESS LIKELY THAN NON-PRACTITIONERS TO USE MEDICATION FOR METABOLIC SYNDROME, MOOD DISORDERS, INFLAMMATION, AND PAIN. CONCLUSIONS: A LONG-TERM YOGA PRACTICE WAS ASSOCIATED WITH LITTLE OR NO OBESITY IN A NON-PROBABILITY SAMPLE OF WOMEN OVER 45 YEARS. RELATIONSHIPS SHOWED A DOSE-RESPONSE EFFECT, WITH INCREASED YOGA EXPERIENCE PREDICTING LOWER BMI AND REDUCED MEDICATION USE.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
3  563  38 CROSS-SECTIONAL ANALYSIS OF HEALTH-RELATED QUALITY OF LIFE AND ELEMENTS OF YOGA PRACTICE. BACKGROUND: MIND-BODY PRACTICES SUCH AS YOGA HAVE BEEN STUDIED FOR THEIR GENERALLY POSITIVE EFFECTS ON HEALTH-RELATED QUALITY OF LIFE (HRQOL). THE ASSOCIATION BETWEEN HOW A PERSON PRACTICES YOGA AND THE PERSON'S HRQOL IS NOT KNOWN. MATERIALS AND METHODS: YOGA PRACTITIONERS WERE SENT INVITATIONS TO PARTICIPATE IN AN ONLINE SURVEY VIA EMAIL. YOGA CHARACTERISTICS, HRQOL, AND OTHER SOCIODEMOGRAPHICS WERE COLLECTED. ANALYSES OF DATA FROM 309 CONSENTING RESPONDERS EVALUATED ASSOCIATIONS BETWEEN YOGA PRACTICE CHARACTERISTICS (USE OF YOGA TOOLS, LENGTH OF PRACTICE, LOCATION, METHOD, ETC.) AND THE 10-ITEM PROMIS GLOBAL HEALTH SCALE FOR BOTH PHYSICAL AND MENTAL HEALTH COMPONENTS. RESULTS: MULTIVARIABLE REGRESSION MODELS DEMONSTRATED HIGHER MENTAL HEALTH SCORES WERE ASSOCIATED WITH REGULAR MEDITATION PRACTICE, HIGHER INCOME, AND THE METHOD OF PRACTICING IN A COMMUNITY GROUP CLASS (VERSUS ONE-ON-ONE). HIGHER PHYSICAL HEALTH SCORES WERE ASSOCIATED WITH LENGTH OF LIFETIME PRACTICE, TEACHER STATUS, KRISHNAMACHARYA YOGA STYLE, AND PRACTICING IN A YOGA SCHOOL/STUDIO (VERSUS AT HOME). CONCLUSIONS: MEDITATION PRACTICE IN YOGA IS POSITIVELY ASSOCIATED WITH MENTAL HEALTH. LENGTH OF LIFETIME YOGA PRACTICE WAS SIGNIFICANTLY ASSOCIATED WITH BETTER PHYSICAL HEALTH, SUGGESTING YOGA HAS A POTENTIAL CUMULATIVE BENEFIT OVER TIME. DIFFERENT LOCATIONS AND METHODS OF PRACTICE MAY BE ASSOCIATED WITH VARYING EFFECTS ON HEALTH OUTCOMES. COMPARATIVE CROSS-SECTIONAL AND LONGITUDINAL STUDIES ON THE VARIATIONS IN YOGA PRACTICE ARE NEEDED TO FURTHER CHARACTERIZE HEALTH BENEFITS OF YOGA.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
4 2054  29 THE ASSOCIATION OF SUDARSHAN KRIYA YOGA FREQUENCY WITH SLEEP QUALITY: A CROSS-SECTIONAL STUDY FROM SINGAPORE. PURPOSE: THERE IS A DEARTH OF EVIDENCE FOR THE RELATIONSHIP BETWEEN YOGIC BREATHING AND SLEEP QUALITY. EVEN LESS IS KNOWN ABOUT PRACTICE FREQUENCY AND BENEFIT. WE INVESTIGATED THE ASSOCIATION OF SUDARSHAN KRIYA YOGA FREQUENCY WITH SLEEP QUALITY AMONGST ADULT PRACTITIONERS. METHODS: IN A CROSS-SECTIONAL INVESTIGATION ON ADULT PRACTITIONERS OF SUDARSHAN KRIYA YOGA IN SINGAPORE, THE PITTSBURGH SLEEP QUALITY INDEX (PSQI) WAS USED TO ASSESS SLEEP QUALITY. SLEEP QUALITY WAS EXAMINED ACROSS THREE CATEGORIES OF PRACTICE FREQUENCY (MONTHLY, WEEKLY, DAILY). A MULTIVARIATE LOGISTIC REGRESSION MODEL WAS USED TO DETERMINE ASSOCIATION. RESULTS: OF 385 ADULTS (241 WOMEN), THE MEAN AGE (SD) WAS 42.5 (9.9) YEARS. IN TOTAL, 32% OF THE SAMPLE (N = 124) WAS IDENTIFIED AS HAVING POOR SQ. AFTER ADJUSTING FOR STUDY COVARIATES, INDEPENDENT ANALYSES REVEALED AN INVERSE ASSOCIATION FOR HIGHER FREQUENCY OF PRACTICE AND LOWER ODDS OF POOR SQ (OR = 0.52; 95% CI = 0.28-0.94). THE P FOR TREND WAS 0.03. CONCLUSION: THE PRACTICE OF YOGIC BREATHING MAY BENEFIT SLEEP QUALITY. FURTHER EXPERIMENTAL INVESTIGATIONS ARE WARRANTED.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
5 2537  37 YOGA EXPERIENCE AS A PREDICTOR OF PSYCHOLOGICAL WELLNESS IN WOMEN OVER 45 YEARS. BACKGROUND: ALTHOUGH HIGH LEVELS OF SUBJECTIVE WELL-BEING (SWB) ARE COMMON IN OLD AGE, A SUBSET OF OLDER INDIVIDUALS IS DISPROPORTIONATELY VULNERABLE TO NEGATIVE AFFECT. YOGA HAS BEEN SHOWN TO HAVE MANY SHORT-TERM BENEFITS, BUT RESEARCHERS HAVE NOT DETERMINED WHETHER A LONG-TERM OR FREQUENT YOGA PRACTICE INCREASINGLY PROTECTS OLDER WOMEN FROM LOW LEVELS OF PSYCHOLOGICAL WELL-BEING. AIMS: THE PURPOSE OF THIS STUDY WAS TO EXAMINE THE EXTENT TO WHICH PSYCHOLOGICAL ATTITUDES, TRANSCENDENCE, MENTAL MASTERY, AND SUBJECTIVE VITALITY IN A SAMPLE OF FEMALE YOGA PRACTITIONERS OVER 45 YEARS VARIED ACCORDING TO THE LENGTH AND FREQUENCY OF YOGA PRACTICE. MATERIALS AND METHODS: WE ADMINISTERED ONLINE SURVEYS TO A NON-PROBABILITY SAMPLE OF 211 FEMALE YOGA PRACTITIONERS 45 TO 80. WE USED WEIGHTED LEAST SQUARES REGRESSION ANALYSES TO EVALUATE THE RELATIONSHIP OF EXTENT OF YOGA EXPERIENCE TO THE OUTCOME VARIABLES AFTER ACCOUNTING FOR AGE AND LIFESTYLE FACTORS. RESULTS: PARTICIPANTS HAD PRACTICED YOGA FOR AS LONG AS 50 YEARS AND FOR UP TO 28 H PER WEEK. THERE WERE SIGNIFICANT POSITIVE RELATIONSHIPS BETWEEN YOGA EXPERIENCE AND ALL OUTCOME VARIABLES. THESE SIGNIFICANT RELATIONSHIPS REMAINED AFTER ACCOUNTING FOR AGE AND LIFESTYLE FACTORS. WHEN WE COMPUTED YOGA EXPERIENCE IN TERMS OF TOTAL CALENDAR YEARS, WITHOUT ACCOUNTING FOR HOURS OF PRACTICE, SIGNIFICANT RELATIONSHIPS DID NOT REMAIN. TRANSCENDENCE OF THE ORDINARY WAS THE MOST STRONGLY ASSOCIATED WITH CURRENT YOGA PRACTICE FREQUENCY, AND POSITIVE PSYCHOLOGICAL ATTITUDES WERE THE MOST STRONGLY ASSOCIATED WITH TOTAL LIFETIME HOURS OF PRACTICE. CONCLUSIONS: AMONG A NON-PROBABILITY SAMPLE OF FEMALE YOGA PRACTITIONERS BETWEEN 45 AND 80 YEARS, INCREASED YOGA EXPERIENCE PREDICTED INCREASED LEVELS OF PSYCHOLOGICAL WELL-BEING. RESULTS SHOWED A DOSE-RESPONSE EFFECT, WITH YOGA EXPERIENCE EXERCISING AN INCREASINGLY PROTECTIVE EFFECT AGAINST LOW LEVELS OF SWB AND VITALITY.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
6 2538  38 YOGA FOR ADULT WOMEN WITH CHRONIC PTSD: A LONG-TERM FOLLOW-UP STUDY. INTRODUCTION: YOGA-THE INTEGRATIVE PRACTICE OF PHYSICAL POSTURES AND MOVEMENT, BREATH EXERCISES, AND MINDFULNESS-MAY SERVE AS A USEFUL ADJUNCTIVE COMPONENT OF TRAUMA-FOCUSED TREATMENT TO BUILD SKILLS IN TOLERATING AND MODULATING PHYSIOLOGIC AND AFFECTIVE STATES THAT HAVE BECOME DYSREGULATED BY TRAUMA EXPOSURE. A PREVIOUS RANDOMIZED CONTROLLED STUDY WAS CARRIED OUT AMONG 60 WOMEN WITH CHRONIC, TREATMENT-RESISTANT POST-TRAUMATIC STRESS DISORDER (PTSD) AND ASSOCIATED MENTAL HEALTH PROBLEMS STEMMING FROM PROLONGED OR MULTIPLE TRAUMA EXPOSURES. AFTER 10 SESSIONS OF YOGA, PARTICIPANTS EXHIBITED STATISTICALLY SIGNIFICANT DECREASES IN PTSD SYMPTOM SEVERITY AND GREATER LIKELIHOOD OF LOSS OF PTSD DIAGNOSIS, SIGNIFICANT DECREASES IN ENGAGEMENT IN NEGATIVE TENSION REDUCTION ACTIVITIES (E.G., SELF-INJURY), AND GREATER REDUCTIONS IN DISSOCIATIVE AND DEPRESSIVE SYMPTOMS WHEN COMPARED WITH THE CONTROL (A SEMINAR IN WOMEN'S HEALTH). THE CURRENT STUDY IS A LONG-TERM FOLLOW-UP ASSESSMENT OF PARTICIPANTS WHO COMPLETED THIS RANDOMIZED CONTROLLED TRIAL. METHODS: PARTICIPANTS FROM THE RANDOMIZED CONTROLLED TRIAL WERE INVITED TO PARTICIPATE IN LONG-TERM FOLLOW-UP ASSESSMENTS APPROXIMATELY 1.5 YEARS AFTER STUDY COMPLETION TO ASSESS WHETHER THE INITIAL INTERVENTION AND/OR YOGA PRACTICE AFTER TREATMENT WAS ASSOCIATED WITH ADDITIONAL CHANGES. FORTY-NINE WOMEN COMPLETED THE LONG-TERM FOLLOW-UP INTERVIEWS. HIERARCHICAL REGRESSION ANALYSIS WAS USED TO EXAMINE WHETHER TREATMENT GROUP STATUS IN THE ORIGINAL STUDY AND FREQUENCY OF YOGA PRACTICE AFTER THE STUDY PREDICTED GREATER CHANGES IN SYMPTOMS AND PTSD DIAGNOSIS. RESULTS: GROUP ASSIGNMENT IN THE ORIGINAL RANDOMIZED STUDY WAS NOT A SIGNIFICANT PREDICTOR OF LONGER-TERM OUTCOMES. HOWEVER, FREQUENCY OF CONTINUING YOGA PRACTICE SIGNIFICANTLY PREDICTED GREATER DECREASES IN PTSD SYMPTOM SEVERITY AND DEPRESSION SYMPTOM SEVERITY, AS WELL AS A GREATER LIKELIHOOD OF A LOSS OF PTSD DIAGNOSIS. CONCLUSIONS: YOGA APPEARS TO BE A USEFUL TREATMENT MODALITY; THE GREATEST LONG-TERM BENEFITS ARE DERIVED FROM MORE FREQUENT YOGA PRACTICE.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
7 2377  28 WHO PRACTICES YOGA? A SYSTEMATIC REVIEW OF DEMOGRAPHIC, HEALTH-RELATED, AND PSYCHOSOCIAL FACTORS ASSOCIATED WITH YOGA PRACTICE. YOGA HAS BECOME INCREASINGLY POPULAR IN THE US AND AROUND THE WORLD, YET BECAUSE MOST YOGA RESEARCH IS CONDUCTED AS CLINICAL TRIALS OR EXPERIMENTS, LITTLE IS KNOWN ABOUT THE CHARACTERISTICS AND CORRELATES OF PEOPLE WHO INDEPENDENTLY CHOOSE TO PRACTICE YOGA. WE CONDUCTED A SYSTEMATIC REVIEW OF THIS ISSUE, IDENTIFYING 55 STUDIES AND CATEGORIZING CORRELATES OF YOGA PRACTICE INTO SOCIODEMOGRAPHICS, PSYCHOSOCIAL CHARACTERISTICS, AND MENTAL AND PHYSICAL WELL-BEING. YOGA USE IS GREATEST AMONG WOMEN AND THOSE WITH HIGHER SOCIOECONOMIC STATUS AND APPEARS FAVORABLY RELATED TO PSYCHOSOCIAL FACTORS SUCH AS COPING AND MINDFULNESS. YOGA PRACTICE OFTEN RELATES TO BETTER SUBJECTIVE HEALTH AND HEALTH BEHAVIORS BUT ALSO WITH MORE DISTRESS AND PHYSICAL IMPAIRMENT. HOWEVER, EVIDENCE IS SPARSE AND METHODOLOGICAL LIMITATIONS PRECLUDE DRAWING CAUSAL INFERENCES. NATIONALLY REPRESENTATIVE STUDIES HAVE MINIMALLY ASSESSED YOGA WHILE STUDIES WITH STRONG ASSESSMENT OF YOGA PRACTICE (E.G., TYPE, DOSE) ARE GENERALLY CONDUCTED WITH CONVENIENCE SAMPLES. ALMOST ALL STUDIES REVIEWED ARE CROSS-SECTIONAL AND FEW CONTROL FOR POTENTIAL CONFOUNDING VARIABLES. WE PROVIDE RECOMMENDATIONS FOR FUTURE RESEARCH TO BETTER UNDERSTAND THE CORRELATES OF YOGA PRACTICE.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
8 1787  33 PREFERENCE AND EXPECTATION FOR TREATMENT ASSIGNMENT IN A RANDOMIZED CONTROLLED TRIAL OF ONCE- VS TWICE-WEEKLY YOGA FOR CHRONIC LOW BACK PAIN. BACKGROUND: IN STUDIES INVOLVING NONPHARMACOLOGICAL COMPLEMENTARY AND ALTERNATIVE MEDICINE INTERVENTIONS, PARTICIPANT BLINDING IS VERY DIFFICULT. PARTICIPANT EXPECTATIONS MAY AFFECT PERCEIVED BENEFIT OF THERAPY. IN STUDIES OF YOGA AS TREATMENT FOR CHRONIC LOW BACK PAIN, LITTLE IS KNOWN ABOUT THE RELATIONSHIP BETWEEN PATIENT EXPECTATIONS AND PREFERENCES ON OUTCOMES. THIS STUDY WAS DESIGNED TO IDENTIFY BASELINE PREDICTORS OF PREFERENCE AND TO DETERMINE IF EXPECTATIONS AND PREFERENCES FOR DIFFERENT DOSES OF YOGA AFFECT BACK-RELATED FUNCTION AND LOW BACK PAIN INTENSITY. METHODS: THIS WAS A SECONDARY DATA ANALYSIS OF A 12-WEEK RANDOMIZED CONTROLLED TRIAL COMPARING ONCE-WEEKLY VS TWICE-WEEKLY YOGA FOR TREATMENT OF CHRONIC LOW BACK PAIN IN 93 ADULTS FROM A PREDOMINANTLY LOW-INCOME MINORITY POPULATION. AT BASELINE, PARTICIPANTS WERE ASKED ABOUT BACK FUNCTION, BACK PAIN, TREATMENT EXPECTATIONS, AND TREATMENT PREFERENCES. WE CREATED A VARIABLE "CONCORDANCE" TO DESCRIBE THE MATCHING OF PARTICIPANT PREFERENCE TO RANDOMIZED TREATMENT. OUR OUTCOME VARIABLES WERE CHANGE IN BACK FUNCTION AND PAIN INTENSITY AFTER 12 WEEKS OF YOGA INSTRUCTION. WE PERFORMED LOGISTIC REGRESSION TO IDENTIFY PREDICTORS OF PREFERENCE FOR ONCE- OR TWICE-WEEKLY YOGA INSTRUCTION. WE CREATED LINEAR REGRESSION MODELS TO IDENTIFY INDEPENDENT ASSOCIATIONS BETWEEN EXPECTATIONS, PREFERENCE, CONCORDANCE, AND OUTCOMES. RESULTS: WORSE BACK FUNCTION AT BASELINE WAS ASSOCIATED WITH 20% HIGHER ODDS OF PREFERRING TWICE-WEEKLY YOGA (OR 1.2, CI 1.1, 1.3). INDIVIDUALS WITH HIGHER EXPECTATION SCORES FOR TWICE-WEEKLY YOGA HAD 90% HIGHER ODDS OF PREFERRING TWICE-WEEKLY VS ONCE-WEEKLY YOGA (OR 1.9, CI 1.3, 2.7). INDIVIDUALS WITH HIGHER EXPECTATION SCORES FOR ONCE-WEEKLY YOGA HAD 40% LESS ODDS OF PREFERRING TWICE-WEEKLY YOGA (OR 0.6, CI 0.5, 0.9). AFTER CONTROLLING FOR BASELINE CHARACTERISTICS, WE FOUND NO STATISTICALLY SIGNIFICANT RELATIONSHIP BETWEEN TREATMENT OUTCOMES, PREFERENCE, EXPECTATION SCORES, OR CONCORDANCE. CONCLUSION: IN A POPULATION OF PREDOMINANTLY LOW-INCOME MINORITY PARTICIPANTS WITH CHRONIC LOW BACK PAIN, WORSE BACK FUNCTION WAS ASSOCIATED WITH PREFERENCE FOR MORE FREQUENT YOGA CLASSES. THOSE WHO PREFERRED MORE YOGA CLASSES HAD HIGHER EXPECTATIONS FOR THOSE CLASSES. TWELVE-WEEK CHANGE IN BACK PAIN INTENSITY AND BACK FUNCTION WERE NOT AFFECTED BY DOSING PREFERENCE, EXPECTATION SCORE, OR CONCORDANCE. MORE RESEARCH IS NEEDED TO BETTER MEASURE AND QUANTIFY PREFERENCE, EXPECTATIONS, AND THEIR RELATIONSHIP TO OUTCOMES IN YOGA RESEARCH.	2015	
                                                                                                                                                                   
9 2370  51 WHAT BRINGS YOUNG ADULTS TO THE YOGA MAT? CROSS-SECTIONAL ASSOCIATIONS BETWEEN MOTIVATIONAL PROFILES AND PHYSICAL AND PSYCHOLOGICAL HEALTH AMONG PARTICIPANTS IN THE PROJECT EAT-IV SURVEY. OBJECTIVES: THIS STUDY EXAMINES MOTIVATIONS FOR YOGA AND IDENTIFIES UNIQUE MOTIVATIONAL PROFILES AMONG A SAMPLE OF YOUNG ADULT YOGA PRACTITIONERS. THIS STUDY FURTHER DETERMINES HOW YOUNG ADULT YOGA PRACTITIONERS' MOTIVATIONAL PROFILES ASSOCIATE WITH PHYSICAL HEALTH BEHAVIORS AND PSYCHOLOGICAL FACTORS. SUBJECTS/SETTING: SURVEY DATA WERE DRAWN FROM THE FOURTH WAVE OF A LARGE, POPULATION-BASED STUDY (PROJECT EAT-IV; EATING AND ACTIVITY IN TEENS AND YOUNG ADULTS). DESIGN: LATENT CLASS ANALYSIS (LCA) WAS USED TO IDENTIFY MOTIVATIONAL PROFILES AMONG PROJECT EAT-IV PARTICIPANTS PRACTICING YOGA (N = 297; MEAN AGE: 30.8-1.7 YEARS; 79.7 % FEMALE). CROSS-SECTIONAL ASSOCIATIONS BETWEEN LATENT MOTIVATIONAL PROFILES, PHYSICAL HEALTH BEHAVIORS, AND PSYCHOLOGICAL FACTORS WERE DETERMINED WITH UNADJUSTED AND ADJUSTED (GENDER, RACE/ETHNICITY, AND BODY MASS INDEX) GENERAL LINEAR MODELS. RESULTS: ACROSS MOTIVATIONAL PROFILES, MOST YOUNG ADULT YOGA PRACTITIONERS WERE MOTIVATED BY ENHANCED FITNESS AND STRESS REDUCTION/RELAXATION. ADDITIONAL MOTIVATIONS FOR YOGA CLUSTERED BY APPEARANCE (DESIRE TO CHANGE BODY APPEARANCE OR WEIGHT) OR MINDFULNESS (DESIRE TO INCREASE PRESENT MOMENT AWARENESS) UNDERPINNINGS. THE LCA CHARACTERIZED MOTIVATIONAL PROFILES AS "LOW APPEARANCE, LOW MINDFULNESS" (CLASS 1; N = 77), "LOW APPEARANCE, HIGH MINDFULNESS" (CLASS 2; N = 48), "HIGH APPEARANCE, LOW MINDFULNESS" (CLASS 3; N = 79), AND "HIGH APPEARANCE, HIGH MINDFULNESS" (CLASS 4; N = 93). HAVING A PROFILE WITH HIGH MINDFULNESS AND LOW APPEARANCE MOTIVATIONS (CLASS 2) WAS ASSOCIATED WITH HIGHER BODY SATISFACTION IN COMPARISON TO THE OTHER CLASSES (P < 0.001). RELATIVE TO CLASS 2, THOSE WITH LOW MINDFULNESS MOTIVATIONS (CLASS 1; CLASS 3) REPORTED LESS TOTAL PHYSICAL ACTIVITY (P = 0.002) AND THOSE WITH HIGH APPEARANCE MOTIVATIONS (CLASS 3; CLASS 4) REPORTED HIGHER COMPULSIVE EXERCISE SCORES (P = 0.002). CONCLUSIONS: IN THIS SAMPLE, HIGH MINDFULNESS AND LOW APPEARANCE MOTIVATIONS FOR YOGA APPEARED OPTIMAL FOR PHYSICAL AND PSYCHOLOGICAL HEALTH. CROSS-SECTIONAL FINDINGS SUGGEST THAT YOUNG ADULT YOGA PRACTITIONERS' MIND-BODY HEALTH MAY BE SUPPORTED BY MOTIVATIONAL UNDERPINNINGS THAT EMPHASIZE YOGA'S INTERNAL (MINDFULNESS) RATHER THAN EXTERNAL (APPEARANCE) BENEFITS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                           
10 2053  38 THE ASSOCIATION BETWEEN YOGA USE, PHYSICAL FUNCTION, AND EMPLOYMENT IN ADULTS WITH RHEUMATOID ARTHRITIS. MIND-BODY EXERCISES SUCH AS YOGA OFFER PATIENTS WITH RHEUMATOID ARTHRITIS (RA) A SYMPTOM MANAGEMENT STRATEGY FOR IMPROVING PHYSICAL AND MENTAL HEALTH. STUDIES HAVE EVALUATED YOGA TO MANAGE SYMPTOMS OF RA AND IMPROVE PHYSICAL FUNCTION; HOWEVER, NONE HAS EXAMINED THE RELATIONSHIP BETWEEN YOGA AND WORK STATUS IN ADULTS WITH RA. THE OBJECTIVE WAS TO DESCRIBE DIFFERENCES IN RA SYMPTOMATOLOGY, PHYSICAL FUNCTION SCORES, AND WORK STATUS BETWEEN ADULTS WITH RA WHO PARTICIPATE IN YOGA AND THOSE WHO DO NOT. THIS CROSS-SECTIONAL STUDY SURVEYED ADULTS WITH RHEUMATOLOGIST-DIAGNOSED RA REGARDING YOGA USE IN THE PAST YEAR, SYMPTOMS, PHYSICAL FUNCTION, AND WORK STATUS. DIFFERENCES BETWEEN YOGA AND NON-YOGA PARTICIPATION GROUPS WERE ASSESSED WITH 2-SIDED T TESTS OR PEARSON CHI TESTS. MULTIVARIATE LINEAR REGRESSION ANALYSES WERE CONDUCTED TO IDENTIFY SIGNIFICANT ASSOCIATIONS BETWEEN YOGA PARTICIPATION AND PRIMARY OUTCOMES. THE SAMPLE INCLUDED 398 ADULTS WITH RA; 88% WERE FEMALES, 66% WERE WHITE, MEAN AGE 61.8 YEARS, MEAN DISEASE DURATION 24.8 YEARS; 10.6% PARTICIPATED IN YOGA. VINYASA, BIKRAM, HATHA, IYENGAR, AND RESTORATIVE YOGA STYLES WERE PRACTICED, MOSTLY IN A GROUP SETTING. YOGA PARTICIPANTS WERE SIGNIFICANTLY MORE LIKELY TO WORK FULL-TIME, LESS LIKELY TO BE UNABLE TO WORK DUE TO DISABILITY, AND HAD BETTER PHYSICAL FUNCTION. THESE FINDINGS CHARACTERIZE YOGA PRACTICE AND PRACTITIONERS AMONG ADULTS WITH RA. IN ADULTS WITH RA, YOGA PARTICIPATION IS ASSOCIATED WITH FULL-TIME WORK STATUS AND BETTER PHYSICAL FUNCTION THAN NONPARTICIPATION. THIS STUDY ADDS ADDITIONAL INFORMATION TO THE GROWING BODY OF LITERATURE ABOUT ADULTS WITH RA WHO PRACTICE YOGA.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
11  357  31 ASSOCIATION BETWEEN SUDARSHAN KRIYA YOGA AND HEALTHY LIFESTYLE PRACTICES AMONG WORKING ADULTS: A CROSS-SECTIONAL STUDY FROM SINGAPORE. OBJECTIVES: THERE IS A PAUCITY OF RESEARCH ON THE ASSOCIATION BETWEEN YOGIC BREATHING AND HEALTHY LIFESTYLE FACTORS IN WORKING ADULTS. ALSO, THERE IS VERY LITTLE INFORMATION ABOUT THE FREQUENCY OF YOGIC BREATHING PRACTICE AND ITS BENEFITS. THE AUTHORS INVESTIGATED THE RELATIONSHIP BETWEEN SUDARSHAN KRIYA YOGA (SKY) FREQUENCY AND THE LIKELIHOOD OF LEADING A HEALTHIER LIFESTYLE AMONG PRACTITIONERS AND NONPRACTITIONERS. DESIGN: CROSS-SECTIONAL INVESTIGATION ON NON-SKY AND SKY PRACTITIONERS, SKY WAS CATEGORIZED INTO NON-, MONTHLY, WEEKLY, AND DAILY PRACTITIONERS. CONFOUNDING VARIABLES INCLUDED AGE, GENDER, ETHNICITY, MARITAL STATUS, AND EDUCATION LEVEL. A MULTIVARIATE LOGISTIC REGRESSION MODEL WAS USED TO COMPARE PRACTICE FREQUENCIES WITH THE ODDS OF HAVING A HEALTHIER LIFESTYLE. SETTINGS: COMMUNITY CENTERS, COMMUNITY EVENTS, WORKPLACES, AND UNIVERSITIES THROUGHOUT SINGAPORE SUBJECTS: OF THE 531 WORKING ADULTS (54.8% FEMALE), 50.1% HAD A HEALTHIER LIFESTYLE >/= 4 HEALTHY LIFESTYLE FACTORS). OUTCOME MEASURE: HAVING A HEALTHIER LIFESTYLE WAS DEFINED AS HAVING >/= 4 HEALTHY LIFESTYLE FACTORS OUT OF SEVEN (SMOKING, ALCOHOL, DIET, EXERCISE, SLEEP, STRESS, AND WEIGHT). RESULTS: MULTIVARIATE ANALYSIS DEMONSTRATED THAT THOSE WHO PRACTICED SKY >/= 4 DAYS/WEEK HAD SIGNIFICANTLY HIGHER ODDS OF HAVING A HEALTHIER LIFESTYLE (ODDS RATIO = 3.62; 95% CONFIDENCE INTERVAL = 2.10-6.23). THE P FOR TREND ANALYSIS DEMONSTRATED THAT AS THE FREQUENCY OF PRACTICE INCREASED THE LIKELIHOOD OF HAVING A HEALTHIER LIFESTYLE ALSO INCREASED ( P < 0.001). CONCLUSION: THE PRACTICE OF YOGIC BREATHING MAY PROMOTE A HEALTHIER LIFESTYLE IN WORKING ADULTS. FURTHER EXPERIMENTAL AND LONGITUDINAL INVESTIGATIONS ARE WARRANTED.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
12 1699  42 PARTICIPANT CHARACTERISTICS ASSOCIATED WITH SYMPTOMATIC IMPROVEMENT FROM YOGA FOR CHRONIC LOW BACK PAIN. CONTEXT: STUDIES SUGGEST THAT YOGA IS EFFECTIVE FOR MODERATE TO SEVERE CHRONIC LOW BACK PAIN (CLBP) IN DIVERSE PREDOMINANTLY LOWER SOCIOECONOMIC STATUS POPULATIONS. HOWEVER, LITTLE IS KNOWN ABOUT FACTORS ASSOCIATED WITH BENEFIT FROM THE YOGA INTERVENTION. OBJECTIVE: IDENTIFY FACTORS AT BASELINE INDEPENDENTLY ASSOCIATED WITH GREATER EFFICACY AMONG PARTICIPANTS IN A STUDY OF YOGA FOR CLBP. DESIGN: FROM SEPTEMBER-DECEMBER 2011, A 12-WEEK RANDOMIZED DOSING TRIAL WAS CONDUCTED COMPARING WEEKLY VS. TWICE-WEEKLY 75-MINUTE HATHA YOGA CLASSES FOR 95 PREDOMINANTLY LOW-INCOME MINORITY ADULTS WITH NONSPECIFIC CLBP. PARTICIPANT CHARACTERISTICS COLLECTED AT BASELINE WERE USED TO DETERMINE FACTORS BEYOND TREATMENT ASSIGNMENT (REPORTED IN THE INITIAL STUDY) THAT PREDICTED OUTCOME. WE USED BIVARIATE TESTING TO IDENTIFY BASELINE CHARACTERISTICS ASSOCIATED WITH IMPROVEMENT IN FUNCTION AND PAIN, AND INCLUDED SELECT FACTORS IN A MULTIVARIATE LINEAR REGRESSION. SETTING: RECRUITMENT AND CLASSES OCCURRED IN AN ACADEMIC SAFETY-NET HOSPITAL AND FIVE AFFILIATED COMMUNITY HEALTH CENTERS IN BOSTON, MASSACHUSETTS. PARTICIPANTS: NINETY-FIVE ADULTS WITH NONSPECIFIC CLBP, AGES RANGING FROM 20-64 (MEAN 48) YEARS; 72 WOMEN AND 23 MEN. OUTCOME MEASURES: PRIMARY OUTCOMES WERE CHANGES IN BACK-RELATED FUNCTION (MODIFIED ROLAND-MORRIS DISABILITY QUESTIONNAIRE, RMDQ; 0-23) AND MEAN LOW BACK PAIN INTENSITY (0-10) IN THE PREVIOUS WEEK, FROM BASELINE TO WEEK 12. RESULTS: ADJUSTING FOR GROUP ASSIGNMENT, BASELINE RMDQ, AGE, AND GENDER, FOREIGN NATIONALITY AND LOWER BASELINE SF36 PHYSICAL COMPONENT SCORE (PCS) WERE INDEPENDENTLY ASSOCIATED WITH IMPROVEMENT IN RMDQ. GREATER THAN HIGH SCHOOL EDUCATION LEVEL, CLBP LESS THAN 1 YEAR, AND LOWER BASELINE SF36 PCS WERE INDEPENDENTLY ASSOCIATED WITH IMPROVEMENT IN PAIN INTENSITY. OTHER DEMOGRAPHICS INCLUDING RACE, INCOME, GENDER, BMI, AND USE OF PAIN MEDICATIONS WERE NOT ASSOCIATED WITH EITHER OUTCOME. CONCLUSIONS: POOR PHYSICAL HEALTH AT BASELINE IS ASSOCIATED WITH GREATER IMPROVEMENT FROM YOGA IN BACK-RELATED FUNCTION AND PAIN. RACE, INCOME, AND BODY MASS INDEX DO NOT AFFECT THE POTENTIAL FOR A PERSON WITH LOW BACK PAIN TO EXPERIENCE BENEFIT FROM YOGA.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
13 1846  31 QUALITY OF LIFE AND MENTAL HEALTH IN PATIENTS WITH CHRONIC DISEASES WHO REGULARLY PRACTICE YOGA AND THOSE WHO DO NOT: A CASE-CONTROL STUDY. WHILE CLINICAL TRIALS HAVE SHOWN EVIDENCE OF EFFICACY OF YOGA IN DIFFERENT CHRONIC DISEASES, SUBJECTIVE HEALTH BENEFITS ASSOCIATED WITH YOGA PRACTICE UNDER NATURALISTIC CONDITIONS HAVE NOT YET BEEN INVESTIGATED. THE AIM OF THIS STUDY WAS TO INVESTIGATE ASSOCIATIONS OF REGULAR YOGA PRACTICE WITH QUALITY OF LIFE AND MENTAL HEALTH IN PATIENTS WITH CHRONIC DISEASES. USING A CASE-CONTROL DESIGN, PATIENTS WITH CHRONIC DISEASES WHO REGULARLY PRACTICED YOGA WERE SELECTED FROM A LARGE OBSERVATIONAL STUDY AND COMPARED TO CONTROLS WHO DID NOT REGULARLY PRACTICE YOGA AND WHO WERE MATCHED INDIVIDUALLY TO EACH CASE ON GENDER, MAIN DIAGNOSIS, EDUCATION, AND AGE (WITHIN 5 YEARS). PATIENTS' QUALITY OF LIFE (SF-36 QUESTIONNAIRE), MENTAL HEALTH (HOSPITAL ANXIETY AND DEPRESSION SCALE), LIFE SATISFACTION, AND HEALTH SATISFACTION (QUESTIONNAIRE FOR LIFE SATISFACTION) WERE ASSESSED. PATIENTS WHO REGULARLY PRACTICED YOGA (N = 186) HAD A BETTER GENERAL HEALTH STATUS (P = 0.012), A HIGHER PHYSICAL FUNCTIONING (P = 0.001), AND PHYSICAL COMPONENT SCORE (P = 0.029) ON THE SF-36 THAN THOSE WHO DID NOT (N = 186). NO GROUP DIFFERENCES WERE FOUND FOR THE MENTAL SCALES OF THE SF-36, ANXIETY, DEPRESSION, LIFE SATISFACTION, OR HEALTH SATISFACTION. IN CONCLUSION, PRACTICING YOGA UNDER NATURALISTIC CONDITIONS SEEMS TO BE ASSOCIATED WITH INCREASED PHYSICAL HEALTH BUT NOT MENTAL HEALTH IN CHRONICALLY DISEASED PATIENTS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
14 1407  32 IMPACT OF YOGA ON INFLAMMATORY BIOMARKERS: A SYSTEMATIC REVIEW. BACKGROUND: MANY CHRONIC CONDITIONS, INCLUDING HEART DISEASE, CANCER, AND RHEUMATOID ARTHRITIS, ARE ASSOCIATED WITH UNDERLYING CHRONIC INFLAMMATORY PROCESSES. LITERATURE REVIEWS HAVE ANALYZED A VARIETY OF INTEGRATIVE THERAPIES AND THEIR RELATIONSHIPS WITH CHRONIC INFLAMMATION. THIS SYSTEMATIC REVIEW IS UNIQUE IN REPORTING SOLELY ON YOGA'S RELATIONSHIP WITH INFLAMMATION. ITS PURPOSE WAS TO SYNTHESIZE CURRENT LITERATURE EXAMINING THE IMPACT OF YOGA INTERVENTIONS ON INFLAMMATORY BIOMARKERS IN ADULTS WITH CHRONIC INFLAMMATORY-RELATED DISORDERS. METHOD: SEARCHES OF SEVERAL ELECTRONIC DATABASES WERE CONDUCTED. INCLUSION CRITERIA WERE (A) ENGLISH LANGUAGE, (B) SAMPLE AGE >18 YEARS OLD, (C) YOGA INTERVENTIONS INVOLVING POSTURES WITH OR WITHOUT YOGA BREATHING AND/OR MEDITATION, AND (D) MEASURED INFLAMMATORY BIOMARKERS. RESULTS: THE FINAL REVIEW INCLUDED 15 PRIMARY STUDIES. OF THESE, SEVEN WERE RATED AS EXCELLENT AND EIGHT AS AVERAGE OR FAIR. THERE WAS CONSIDERABLE VARIABILITY IN YOGA TYPES, COMPONENTS, FREQUENCY, SESSION LENGTH, INTERVENTION DURATION, AND INTENSITY. THE MOST COMMON BIOMARKERS MEASURED WERE INTERLEUKIN-6 ( N = 11), C-REACTIVE PROTEIN ( N = 10), AND TUMOR NECROSIS FACTOR ( N = 8). MOST STUDIES REPORTED POSITIVE EFFECTS ON INFLAMMATORY BIOMARKERS ( N = 11) FROM BASELINE TO POST YOGA INTERVENTION. ANALYSIS OF THE DOSE SHOWED HIGHER TOTAL DOSE (>1,000 MIN) RESULTED IN GREATER IMPROVEMENTS IN INFLAMMATION. CONCLUSION: THIS REVIEW SUGGESTS THAT YOGA CAN BE A VIABLE INTERVENTION TO REDUCE INFLAMMATION ACROSS A MULTITUDE OF CHRONIC CONDITIONS. FUTURE STUDIES WITH DETAILED DESCRIPTIONS OF YOGA INTERVENTIONS, MEASUREMENT OF NEW AND WELL-ESTABLISHED INFLAMMATORY BIOMARKERS, AND LARGER SAMPLE SIZES ARE WARRANTED TO ADVANCE THE SCIENCE AND CORROBORATE RESULTS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
15  636  21 DISTRESS TOLERANCE AS A PREDICTOR OF ADHERENCE TO A YOGA INTERVENTION: MODERATING ROLES OF BMI AND BODY IMAGE. THIS STUDY TESTED WHETHER DISTRESS TOLERANCE, BODY IMAGE, AND BODY MASS INDEX (BMI) PREDICTED ADHERENCE TO A YOGA INTERVENTION. PARTICIPANTS WERE 27 WOMEN WHO PARTICIPATED IN A YOGA INTERVENTION AS PART OF A RANDOMIZED CONTROLLED TRIAL. ATTENDANCE AND DISTRESS TOLERANCE WERE ASSESSED WEEKLY, AND BODY IMAGE AND BMI WERE MEASURED AT BASELINE. MULTILEVEL MODELING REVEALED A THREE-WAY INTERACTION OF DISTRESS TOLERANCE, BMI, AND BODY IMAGE (P < .001). FOR PARTICIPANTS WITH FEW BODY IMAGE CONCERNS, DISTRESS TOLERANCE WAS POSITIVELY ASSOCIATED WITH ADHERENCE REGARDLESS OF BMI (P = .009). HOWEVER, FOR THOSE WITH POOR BODY IMAGE, INCREASES IN DISTRESS TOLERANCE WERE ASSOCIATED WITH INCREASES IN ADHERENCE AMONG OVERWEIGHT PARTICIPANTS (P < .001) BUT LOWER ADHERENCE AMONG OBESE PARTICIPANTS (P = .007). DISTRESS TOLERANCE MAY BE IMPLICATED IN ADHERENCE TO A YOGA INTERVENTION, ALTHOUGH ITS EFFECTS MAY BE DEPENDENT ON BODY IMAGE CONCERNS, BMI, AND THEIR INTERACTION. RESEARCH AND CLINICAL IMPLICATIONS ARE DISCUSSED.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
16 2754  42 YOGA PRACTICE PREDICTS IMPROVEMENTS IN DAY-TO-DAY PAIN IN WOMEN WITH METASTATIC BREAST CANCER. CONTEXT: WOMEN WITH METASTATIC BREAST CANCER (MBC) EXPERIENCE A SIGNIFICANT SYMPTOM BURDEN, INCLUDING CANCER PAIN. YOGA IS A MIND-BODY DISCIPLINE THAT HAS SHOWN PROMISE FOR ALLEVIATING CANCER PAIN, BUT FEW STUDIES HAVE INCLUDED PATIENTS WITH METASTATIC DISEASE OR EXAMINED THE ACUTE EFFECTS OF YOGA PRACTICE. OBJECTIVES: TO DETERMINE WHETHER DAILY PAIN CHANGED SIGNIFICANTLY DURING A RANDOMIZED CONTROLLED TRIAL OF THE MINDFUL YOGA PROGRAM AMONG WOMEN WITH MBC AND WHETHER TIME SPENT IN YOGA PRACTICE WAS RELATED TO DAILY PAIN. METHODS: ON ALTERNATE WEEKS DURING THE INTERVENTION PERIOD, WE COLLECTED DAILY MEASURES OF PAIN FROM A SUBSET OF 48 WOMEN RANDOMIZED TO EITHER YOGA (N = 30) OR A SUPPORT GROUP CONDITION (N = 18). WE ALSO ASSESSED DAILY DURATION OF YOGA PRACTICE AMONG PATIENTS RANDOMIZED TO YOGA. RESULTS: PAIN LEVELS WERE LOW FOR WOMEN IN BOTH CONDITIONS, AND NO DIFFERENTIAL TREATMENT EFFECTS WERE FOUND ON DAILY PAIN. HOWEVER, AMONG WOMEN RANDOMIZED TO YOGA, A DOSE/RESPONSE RELATIONSHIP WAS FOUND BETWEEN YOGA PRACTICE DURATION AND DAILY PAIN. WHEN PATIENTS HAD SPENT RELATIVELY MORE TIME PRACTICING YOGA ACROSS TWO CONSECUTIVE DAYS, THEY WERE MORE LIKELY TO EXPERIENCE LOWER PAIN ON THE NEXT DAY. THIS FINDING IS CONSISTENT WITH AN EARLIER MBC STUDY. MEDITATION PRACTICE SHOWED THE STRONGEST ASSOCIATION WITH LOWER DAILY PAIN. CONCLUSION: FINDINGS SUGGEST THAT YOGA PRACTICE (MEDITATION PRACTICE IN PARTICULAR) IS ASSOCIATED WITH ACUTE IMPROVEMENTS IN CANCER PAIN, AND THAT YOGA INTERVENTIONS MAY BE MORE IMPACTFUL IF TESTED IN A SAMPLE OF PATIENTS WITH ADVANCED CANCER IN WHICH PAIN IS RELATIVELY ELEVATED.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
17  291  39 ADVERSE EFFECTS OF YOGA: A NATIONAL CROSS-SECTIONAL SURVEY. BACKGROUND: WHILE YOGA IS INCREASINGLY USED FOR HEALTH PURPOSES, ITS SAFETY HAS BEEN QUESTIONED. THE AIM OF THIS CROSS-SECTIONAL SURVEY WAS TO ANALYZE YOGA-ASSOCIATED ADVERSE EFFECTS AND THEIR CORRELATES. METHODS: A CROSS-SECTIONAL ANONYMOUS NATIONAL ONLINE SURVEY AMONG GERMAN YOGA PRACTITIONERS (N = 1702; 88.9% FEMALE; 47.2 +/- 10.8 YEARS) WAS CONDUCTED FROM JANUARY TO JUNE 2016. PARTICIPANTS WERE QUERIED REGARDING THEIR YOGA PRACTICE, I.E. YOGA STYLES USED, LENGTH AND INTENSITY OF YOGA PRACTICE, PRACTICE PATTERNS, AND WHETHER THEY HAD EXPERIENCED ACUTE OR CHRONIC ADVERSE EFFECTS OF THEIR YOGA PRACTICE. INDEPENDENT PREDICTORS OF ACUTE OR CHRONIC ADVERSE EFFECTS WERE IDENTIFIED USING MULTIPLE LOGISTIC REGRESSION ANALYSES. RESULTS: ASHTANGA YOGA (15.7%), TRADITIONAL HATHA YOGA (14.2%), AND SIVANANDA YOGA (22.4%) WERE THE MOST COMMONLY USED YOGA STYLES. 364 (21.4%) YOGA USERS REPORTED 702 ACUTE ADVERSE EFFECTS, OCCURRING AFTER A MEAN OF 7.6 +/- 8.0 YEARS OF YOGA PRACTICE. THE MOST COMMONLY REPORTED YOGA PRACTICES THAT WERE ASSOCIATED WITH ACUTE ADVERSE EFFECTS WERE HAND-, SHOULDER- AND HEAD STANDS (29.4%). USING VINIYOGA WAS ASSOCIATED WITH A DECREASED RISK OF ACUTE ADVERSE EFFECTS; PRACTICING ONLY BY SELF-STUDY WITHOUT SUPERVISION WAS ASSOCIATED WITH HIGHER RISK. ONE HUNDRED SEVENTY-THREE PARTICIPANTS (10.2%) REPORTED 239 CHRONIC ADVERSE EFFECTS. THE RISK OF CHRONIC ADVERSE EFFECTS WAS HIGHER IN PARTICIPANTS WITH CHRONIC ILLNESSES AND THOSE PRACTICING ONLY BY SELF-STUDY WITHOUT SUPERVISION. MOST REPORTED ADVERSE EFFECTS CONCERNED THE MUSCULOSKELETAL SYSTEM. 76.9% OF ACUTE CASES, AND 51.6% OF CHRONIC CASES REACHED FULL RECOVERY. ON AVERAGE 0.60 INJURIES (95% CONFIDENCE INTERVAL = 0.51-0.71) PER 1000 H OF PRACTICE WERE REPORTED, WITH POWER YOGA USERS REPORTING THE HIGHEST RATE (1.50 INJURIES PER 1000 H; 95% CONFIDENCE INTERVAL = 0.98-3.15). CONCLUSIONS: ONE IN FIVE ADULT YOGA USERS REPORTED AT LEAST ONE ACUTE ADVERSE EFFECT IN THEIR YOGA PRACTICE, AND ONE IN TEN REPORTED AT LEAST ONE CHRONIC ADVERSE EFFECT, MAINLY MUSCULOSKELETAL EFFECTS. ADVERSE EFFECTS WERE ASSOCIATED WITH HAND-, SHOULDER- AND HEAD STANDS; AND WITH YOGA SELF-STUDY WITHOUT SUPERVISION. MORE THAN THREE QUARTERS OF OF CASES REACHED FULL RECOVERY. BASED ON THE OVERALL INJURY RATE PER 1000 PRACTICE HOURS, YOGA APPEARS TO BE AS SAFE OR SAFER WHEN COMPARED TO OTHER EXERCISE TYPES.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                        
18 2749  44 YOGA PRACTICE IN THE UK: A CROSS-SECTIONAL SURVEY OF MOTIVATION, HEALTH BENEFITS AND BEHAVIOURS. OBJECTIVES: DESPITE THE POPULARITY OF YOGA AND EVIDENCE OF ITS POSITIVE EFFECTS ON PHYSICAL AND MENTAL HEALTH, LITTLE IS KNOWN ABOUT YOGA PRACTICE IN THE UK. THIS STUDY INVESTIGATED THE CHARACTERISTICS OF PEOPLE WHO PRACTISE YOGA, REASONS FOR INITIATING AND MAINTAINING PRACTICE, AND PERCEIVED IMPACT OF YOGA ON HEALTH AND WELL-BEING. DESIGN, SETTING AND PARTICIPANTS: A CROSS-SECTIONAL ONLINE ANONYMOUS SURVEY DISTRIBUTED THROUGH UK-BASED YOGA ORGANISATIONS, STUDIOS AND EVENTS, THROUGH EMAIL INVITES AND FLYERS. 2434 YOGA PRACTITIONERS COMPLETED THE SURVEY, INCLUDING 903 YOGA TEACHERS: 87% WERE WOMEN, 91% WHITE AND 71% DEGREE EDUCATED; MEAN AGE WAS 48.7 YEARS. MAIN OUTCOME MEASURES: PERCEIVED IMPACT OF YOGA ON HEALTH CONDITIONS, HEALTH OUTCOMES AND INJURIES. RELATIONSHIPS BETWEEN YOGA PRACTICE AND MEASURES OF HEALTH, LIFESTYLE, STRESS AND WELL-BEING. RESULTS: IN COMPARISON WITH NATIONAL POPULATION NORMS, PARTICIPANTS REPORTED SIGNIFICANTLY HIGHER WELL-BEING BUT ALSO HIGHER ANXIETY; LOWER PERCEIVED STRESS, BODY MASS INDEX AND INCIDENCE OF OBESITY, AND HIGHER RATES OF POSITIVE HEALTH BEHAVIOURS. 47% REPORTED CHANGING THEIR MOTIVATIONS TO PRACTISE YOGA, WITH GENERAL WELLNESS AND FITNESS KEY TO INITIAL UPTAKE, AND STRESS MANAGEMENT AND SPIRITUALITY IMPORTANT TO CURRENT PRACTICE. 16% OF PARTICIPANTS REPORTED STARTING YOGA TO MANAGE A PHYSICAL OR MENTAL HEALTH CONDITION. RESPONDENTS REPORTED THE VALUE OF YOGA FOR A WIDE RANGE OF HEALTH CONDITIONS, MOST NOTABLY FOR MUSCULOSKELETAL AND MENTAL HEALTH CONDITIONS. 20.7% REPORTED AT LEAST ONE YOGA-RELATED INJURY OVER THEIR LIFETIME. CONTROLLING FOR DEMOGRAPHIC FACTORS, FREQUENCY OF YOGA PRACTICE ACCOUNTED FOR SMALL BUT SIGNIFICANT VARIANCE IN HEALTH-RELATED REGRESSION MODELS (P<0.001). CONCLUSION: THE FINDINGS OF THIS FIRST DETAILED UK SURVEY WERE CONSISTENT WITH SURVEYS IN OTHER WESTERN COUNTRIES. YOGA WAS PERCEIVED TO HAVE A POSITIVE IMPACT ON PHYSICAL AND MENTAL HEALTH CONDITIONS AND WAS LINKED TO POSITIVE HEALTH BEHAVIOURS. FURTHER INVESTIGATION OF YOGA'S ROLE IN SELF-CARE COULD INFORM HEALTH-RELATED CHALLENGES FACED BY MANY COUNTRIES.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
19 1658  37 MUSCULOSKELETAL PAIN ASSOCIATED WITH RECREATIONAL YOGA PARTICIPATION: A PROSPECTIVE COHORT STUDY WITH 1-YEAR FOLLOW-UP. BACKGROUND: YOGA IS A POPULAR COMPLEMENTARY THERAPY FOR MUSCULOSKELETAL PAIN. THERE ARE FEW STUDIES HOWEVER, THAT HAVE EXAMINED THE RISKS OF RECREATIONAL PARTICIPATION FOR CAUSING MUSCULOSKELETAL PAIN. OBJECTIVES: TO EXAMINE THE RELATIONSHIP BETWEEN MUSCULOSKELETAL PAIN AND RECREATIONAL YOGA PARTICIPATION. METHODS: THIS WAS A PROSPECTIVE COHORT STUDY WITH ONE-YEAR FOLLOW-UP. DATA WERE COLLECTED VIA ELECTRONIC QUESTIONNAIRES, ONE YEAR APART. OUTCOMES INCLUDED INCIDENCE AND IMPACT OF PAIN CAUSED BY YOGA AND PREVALENCE OF PAIN CAUSED, EXACERBATED, UNAFFECTED, AND IMPROVED BY YOGA. PREDICTORS INCLUDED AGE, EXPERIENCE, HOURS OF PARTICIPATION, AND INTENSITY OF PARTICIPATION. RESULTS: THE FINAL SAMPLE INCLUDED 354 PARTICIPANTS FROM TWO SUBURBAN YOGA STUDIOS. THE INCIDENCE RATE OF PAIN CAUSED BY YOGA WAS 10.7%. MORE THAN ONE-THIRD OF INCIDENT CASES RESULTED IN LOST YOGA PARTICIPATION TIME AND/OR SYMPTOMS LASTING MORE THAN 3 MONTHS. NONE OF THE RISK FACTORS AT BASELINE INCREASED THE RISK FOR SUBSEQUENT INCIDENT CASES OF PAIN CAUSED BY YOGA. CONCLUSIONS: YOGA CAN CAUSE MUSCULOSKELETAL PAIN. PARTICIPANTS MAY BENEFIT FROM DISCLOSURE OF PRACTICE TO THEIR HEALTHCARE PROFESSIONALS AND BY INFORMING TEACHERS OF INJURIES THEY MAY HAVE PRIOR TO PARTICIPATION. YOGA TEACHERS SHOULD ALSO DISCUSS THE RISKS FOR INJURY WITH THEIR STUDENTS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
20 2850  41 YOGA, MINDFULNESS-BASED STRESS REDUCTION AND STRESS-RELATED PHYSIOLOGICAL MEASURES: A META-ANALYSIS. BACKGROUND AND OBJECTIVES: PRACTICES THAT INCLUDE YOGA ASANAS AND MINDFULNESS-BASED STRESS REDUCTION FOR THE MANAGEMENT OF STRESS ARE INCREASINGLY POPULAR; HOWEVER, THE NEUROBIOLOGICAL EFFECTS OF THESE PRACTICES ON STRESS REACTIVITY ARE NOT WELL UNDERSTOOD. MANY STUDIES INVESTIGATING THE EFFECTS OF SUCH PRACTICES FAIL TO INCLUDE AN ACTIVE CONTROL GROUP. GIVEN THE FREQUENCY WITH WHICH PEOPLE ARE SELECTING SUCH INTERVENTIONS AS A FORM OF SELF-MANAGEMENT, IT IS IMPORTANT TO DETERMINE THEIR EFFECTIVENESS. THUS, THIS REVIEW INVESTIGATES THE EFFECTS OF PRACTICES THAT INCLUDE YOGA ASANAS, WITH AND WITHOUT MINDFULNESS-BASED STRESS REDUCTION, COMPARED TO AN ACTIVE CONTROL, ON PHYSIOLOGICAL MARKERS OF STRESS. MATERIALS AND METHODS: A SYSTEMATIC REVIEW AND META-ANALYSIS OF RANDOMISED CONTROLLED TRIALS PUBLISHED IN ENGLISH COMPARED PRACTICES THAT INCLUDED YOGA ASANAS, WITH AND WITHOUT MINDFULNESS-BASED STRESS REDUCTION, TO AN ACTIVE CONTROL, ON STRESS-RELATED PHYSIOLOGICAL MEASURES. THE REVIEW FOCUSED ON STUDIES THAT MEASURED PHYSIOLOGICAL PARAMETERS SUCH AS BLOOD PRESSURE, HEART RATE, CORTISOL AND PERIPHERAL CYTOKINE EXPRESSION. MEDLINE, AMED, CINAHL, PSYCINFO, SOCINDEX, PUBMED, AND SCOPUS WERE SEARCHED IN MAY 2016 AND UPDATED IN DECEMBER 2016. RANDOMISED CONTROLLED TRIALS WERE INCLUDED IF THEY ASSESSED AT LEAST ONE OF THE FOLLOWING OUTCOMES: HEART RATE, BLOOD PRESSURE, HEART RATE VARIABILITY, MEAN ARTERIAL PRESSURE, C-REACTIVE PROTEIN, INTERLEUKINS OR CORTISOL. RISK OF BIAS ASSESSMENTS INCLUDED SEQUENCE GENERATION, ALLOCATION CONCEALMENT, BLINDING OF ASSESSORS, INCOMPLETE OUTCOME DATA, SELECTIVE OUTCOME REPORTING AND OTHER SOURCES OF BIAS. META-ANALYSIS WAS UNDERTAKEN USING COMPREHENSIVE META-ANALYSIS SOFTWARE VERSION 3. SENSITIVITY ANALYSES WERE PERFORMED USING 'ONE-STUDY-REMOVED' ANALYSIS. SUBGROUP ANALYSIS WAS CONDUCTED FOR DIFFERENT YOGA AND CONTROL GROUP TYPES, INCLUDING MINDFULNESS-BASED STRESS REDUCTION VERSUS NON-MINDFULNESS-BASED STRESS REDUCTION BASED INTERVENTIONS, DIFFERENT POPULATIONS, LENGTH OF INTERVENTION, AND METHOD OF DATA ANALYSIS. A RANDOM-EFFECTS MODEL WAS USED IN ALL ANALYSES. RESULTS: FORTY TWO STUDIES WERE INCLUDED IN THE META-ANALYSIS. INTERVENTIONS THAT INCLUDED YOGA ASANAS WERE ASSOCIATED WITH REDUCED EVENING CORTISOL, WAKING CORTISOL, AMBULATORY SYSTOLIC BLOOD PRESSURE, RESTING HEART RATE, HIGH FREQUENCY HEART RATE VARIABILITY, FASTING BLOOD GLUCOSE, CHOLESTEROL AND LOW DENSITY LIPOPROTEIN, COMPARED TO ACTIVE CONTROL. HOWEVER, THE REPORTED INTERVENTIONS WERE HETEROGENEOUS. CONCLUSIONS: PRACTICES THAT INCLUDE YOGA ASANAS APPEAR TO BE ASSOCIATED WITH IMPROVED REGULATION OF THE SYMPATHETIC NERVOUS SYSTEM AND HYPOTHALAMIC-PITUITARY-ADRENAL SYSTEM IN VARIOUS POPULATIONS.	2017
